A guy put in a Oatey PVC 40 Mil Shower Pan Liner a few months back. I am
just about to tile and I notice that it is leaking where the claming flange
and the subtrain connect. I pulled the flange off and I think he used
Henry's 208 to seal it up. Smells and feels like it! That is a no no I
think. Solvent based. Oatey recommends Silicone but not sure how it cures
as it has no air where the joint meets?? Anyway. Now I have Henry's I think
on the top of the bottom flange and on the top flange. Got most of it off.
What do I use now to seal it up?????? Please help. This is holding up my

Some silicones cure by reacting with moisture (liberating acetic acid in the
If you tile over silicones there may be an adhesion problem.
I realize you're working with an existing situation but for future reference
next time you do a shower pan for tile try pouring fibreglass. We've been
doing this here at the Jersey shore for over 30 years and rarely get a leak,
beats PVC or lead. Use a cast iron J.R. Smith drain fitting. It has a
beveled edge that works beautifully by building up the floor even with it
(make it thick so there is no movement in it), pitched toward the center of
the drain, and catting the studs at least 6" off the floor, then pouring 2
layers of fibreglass over it, making sure the beveled edge of the drain is
encased in the fibreglass. If it's done right it will never leak.
If at first you don't suceed it may be time to call a professional.
A $100.00 service call for consultation purposes is cheaper than the
potential damage you may do based on the advice from novices. Choose
your teachers well and remember you get what you pay for.
Considering the scope of the damage that can result from a leak under
a shower pan it couldn't hurt to consult with a professional plumber.
The $100.00 for the service call/consultation would be a wise
investment but finding one is difficult. Many licensed plumbing
contractors have misconceptions about various aspects of plumbing,
shower pan liners notwithstanding.
Choose your teachers well and remember you get what you pay for!
